Ubuntu – How to enable GRUB when using dual boot Windows 10


I have Ubuntu 14.04.1 dual booted with Windows 10. Everytime I switch my notebook on, I have to press F9, go to Boot manager, press Ubuntu and then GRUB menu is shown. I want GRUB to show when I start my notebook. Is there a way to do so ? If I don't press F9,Windows 10 is booted. I have disabled Fast Startup of Windows 10.

Best Answer

I have once had a similar problem with dual-booting with Microsoft Windows.

I solved the issue by taking the following steps.

  1. Boot into Ubuntu.
  2. Hold CTRL-ALT-T to open a terminal
  3. Run:sudo update-grub2 and allow GRUB to update it's list of operating systems.
  4. Close Terminal.
  5. Restart Computer.

Alternatively one could install and use boot repair HERE

This should hopefully sort out the problem and show GRUB upon start up instead of Windows Boot Manager. Good luck.
